when crowd gathered around jesus, then Jesus said: "this generation is bad generation. they want a sign from heaven, but they will not be given a sign except sign of the prophet Jonah. because Jonah become a sign to niniwe people, so also the son of man will become a sign to this generation. at the time of Judgement, the queen of the south will rise up with the men of this generation and they will punish bad people. because her came from the south of the earth to hear the wisdom of Solomon, and indeed at here is more than Solomo! and at the time of judgments, the people of Nineveh will rise up with this generation and they will do punishment. because the people of Nineveh they repented after hear the preaching of Jonah, and indeed at here is greater than Jonah!"
